Be it'v known itlmtsl, wWILL-IAM A.' TUR- nAYNE,`a..citizen ofthe United States, anda resident-.of Inincastencounty of Erie, and State of lNew York, have invented certain new and useful .Improvements in Electrical in which u. .storage buttery and b'ooster areemployed in connection with a rotary converter orother i'ectifyin-g device to steady the load on the main alterna-ting current generator. The principal improvements herein shown in connection with this system apply tothe Vproper rectification of currents of the regulating portion of the system. These improvements are not, in their broadest sense, limited to this general character of a sti-'stem but muy be applied vto other regulatingcircuits Wl-1ere rectification of a regulating current is desi-red.

Various objects of my invention are to provided regulating appuratus in which the regulation is properly proportional to the changes 'to be compensated for, to av-'oid sparking und other t-i-'oubles incidel-lt to the common -cnmutating devices, und generally, to provide bett-cr and more cici-eln't regulation. T10 these ends I provide in the regulating circuitI a rectier having windings connected to the alternating Vcurrent and the direct currentsi'desof 4the reguloting portion's of the syst-em, such windings being in inductive relation to magnetizablemuterial und so arranged thzvt. substantially all the lilou .insaid rechi-fier is produced by the current in' said windings. `This contributes te the provision of 'n rectifier 'substantially devoid of motor act-ion and sparking 'andothcr troubles tire material-ly decreased. In the present vinstance the rectifier is driven in synchronism iwith the alternating currentV of the systeniby a synchronous motor mechanically connected thereto. These and more .specific fen-tores of :my Vinvention will be more fully understood from the detailed description given below taken in .connection with the accompanying drawing forming a part of this specification.

In the drawing, Figure 1. isc diagram showing a. system embodying one form of 'y of my nuproved rectlfying devloe.

'A is an alternating current 4generator hayL ing the circuit conductors 1, 2, 3. (lhcse improvements. Fig'. 2 is' an illustration;`

conductors feed an alternating current cire. j.;

cui-t 7, 8, 9 and also conductors 4, 5, 6, con

nected to the primary of a transformer K the secondary of which is connected by conductors 10, 11 and 12 to the rectifying dc-v vice B, here indicated as a rotary converter l --proximately constant speed, and for" this purpose I have indicated an induction motor H mechanically connected thereto jandre ceiving its power from .the second aryof transformer K.

F is the field of the booster which is rgulated by the result-ant of two-opposing 'pc'- tental differences, .one of'the'se opposing' potential differences being that'ofa 's cial dynemoG which is frequently known 1n.the art as a counter electrornotive force machine'. This machine is in series with the booster field' F. The voltage on the latter und therefore the current therein and the voltage.4

of 'the booster is dependent on the relation. pfthe'electromotive force of G and the opposing potent-ial differences across the ter'- minals of thecircui-t in which G and-F' are located.

G' Vis a. field coil for the counter machin The' cl'lrrentinthe coil Gl is murdeto vary' in accordance with the condition of .the 10.0

ternating current circuitand preferably in direct accordance with the' variations of cur'- A rent .inf'the 'circuit 1, 2, 3. "This I accomplish by providing a series transformer L, ,the primary of which is included in the .circl'lit 1, 2, 3,.whi1ethe secondary is connectedde ,lm

conductors 16, to the alternatngcurrentylf-,n

of the rectifyiug device I), whiclnlof course, is a comparatively small machine. The di rect current end of this rectifying device is connected by conductors 17 to the terminals of the field winding IG so that the rectifying device or rotary converter D is an exciter for the counter machine G. To positively maintain synchronism ythis rectifying device D ismechanically connected to a synchronousmotor C which is connected to, the'conduc-tors 10, 11, and 19. by conductors 15. C is a field coil of the synchronous motor C. This field coil is excited through any suitf ablel direct current source, the diagram illustrat-lng it as connected across the direct current circuit, 13, 14.

,Itwill be seen that any fiuctuation of current on the alternating current generator, Whether due tofiuctuations of load on the alternating current workcir'cuit 7, 8, 9, or-

to fluctuating load on the direct current side of the system, or to changes of battery condition, will correspondingly affect the current in the circuit 16 and in the circuit 17 thusvarying the counter machine field in accordance with the changes of load on the alternating current'generator. f The variation of the' counter machine' field will cause the .electromotive force of the counter machine to vary accordingly and' preferably thiscounter machine shouldbe designed so that these variations of electromotive force arefrom a point below that acting uponthe circuit including F and G to a point above that acting on said circuit, thus makin the booster F reversible and varying its vo tage in accordance with the load on the alternatingcurrent generator. Thus the voltage. of the booster is primarily affected by changes of load on generator A acting through the rectifying device on the field G of the counter machine. This regulation of the -counter machine from the alternating current circuit, causing the booster field to vary `in accordance with the current 'in the alternating current generator, produces a battery current thattfi'vill maintain a-substantial constancy of current of the alternating current4 generator despite fiuctuations of load in the Working circuit, and despite changes of condition of battery, in the same way that the Stora e bat-teri'esawithboosters have -hereto- 'discharge ofthe battery. This discharge leaving the current of the main generato-r butl slightly changed. In the same Way, a decrease of current from the generator A from the average to which the system is adjusted, by reducing the electromotiveforce of the counter machine G causes an electromotive-force of the booster in a direction to oppose a discharge of the battery. Under these circumstances current from the generator will pass through the rotary converter B to charge the battery. As already briefiy pointed out such a system of regulation is very materially improved bythe provision of a Arectifier 'in the regulating circuits Which has very little or substantially no motor action so that it will not tend to pump back on to the line during light loads. To this end I provide the rectifier shown diagramma-tically in detail in Fig. 2 and in which M represents an armature of magnetic material having thereon the distrib- 4uted windings, N. This armature with its windings revolves between the skeleton mag netizable field poles P. By skeleton mag netizable field poles I mean field pole project-ions of magnetizable material or capable o f being magnetized but having no windings thereon which produce any useful flux such as is ordinarilyproduced by the main field Windings'in a common direct cur- -rent generator, and which field -pole projections serve to concentrate the flux other- Wise produced in the device. The field poles P are secured to the structure O'of magnetic material but neither the structure O nor the field poles P have any magnetizing windings thereon,l All the magnetic` fiun. therefore, is produced by the current that 1s being rectified, so that there is no extraneous field to produce such a generator or motor action as will disturb the proper proportionalitybetween the regulating currents and the currents of generator A. e

The alternating three phase regulating current. is delivered to the regulating rectifier D by means of the conductors 16 and the usual slip rings. The direct regulating current is taken therefrom by means of the. commutator segments Q., brushes R and conductors 17. l

The alternating three phase regulating current sets -up a yflux in the armature M which rotates relatively thereto. This finan' however, is kept stationary .because of the Fra opposite rotation of the armature by the s nchronous motor 16. Thus thepositi'on of t e flux becomes fixed Y'audit is gathered up 'by the skeletonvfield poles P." The brushes" R are placed at the points E of maximumV Adif-v ference "of potential of the-windings `N and the cui'freifitl in coil '.G `is'therefore properly proportioned pto the alternating' regulating current.` y x Althoughl have shown the synchronous motor@ 'las rotating the armature M and its wmdings H, the' 'same eifect @may be had by l rotating the commutator .brushes and field structure vsynehronously with' the alternatingcurrent and ellowinthe windings N to reinem'stationary.Y `In t is case'thebrushes Rf'wouldfollow the rotating iux'and would take ofi' current from the windings N at the. points o f maximum difference of potential l as before. lt'is thusevident thatv many' Ghengesma. be made inthe system without departing rom the spirit of my invention and, therefore, I do 4not limit myself to the particular details described;
